基于矢量水听器的非均匀阵列A PES波束形成算法
Non-uniform Array Vector-APES Beamforming Algorithm Based on Vector-Hydrophone
摘要
Abstract
Since conventional amplitude and phase estimation (APES ) algorithm cannot be applied to a non‐uniform array ,a vector APES(VAPES) based on vector‐hydrophone is proposed .The phase differ‐ence between acoustic pressure and acoustic particle velocity received by vector‐hydrophone is irrelative to the locations of sensors ,thus the pressure and velocity channel can be used as two sub‐arrays ,and ap‐plied to non‐uniform array .The array gain and its stability are analyzed .The simulations indicate that compared to conventional APES algorithm ,the method can be applied to non‐uniform array ,and its array gain is higher ;compared to minimum variance distortionless response (MVDR) algorithm ,the method is more robust ,can handle the coherent situation ,and abtain more accrate signal power .The practical data verifies the validity of VAPES .关键词
